The integration of such high-resolution borehole images (BHI) with data from vintage tools as well as core and seismic allows for an advanced interpretation of structural dip and depositional environment, being valuable particularly in challenging areas such as the Mississippi Canyon, Gulf of Mexico. The latest BHI data is used to verify previous hypotheses for the interpretation of the structural dip within the Thunder Horse field. The Thunder Horse reservoir interval is characterized by mass transport deposits, where the majority of mud-prone beds represent slump units and slide blocks of variable orientation. Therefore these mudstones cannot be used as paleo-horizontal indicator. Conversely, intercalated turbiditic sands with parallel layering are sought as reference for paleo-horizontal. As a consequence, the halokinetic tilting near the Thunder Horse North salt wall is analyzed from stereographic projections of these sand units instead. After restoring the pre-halokinetic bedding dip a S to SSE directed sediment transport is interpreted for these Middle Miocene reservoirs, hence excluding a salt barrier or deflection of the turbiditic currents.","PeriodicalId":427666,"journal":{"name":"Third EAGE Borehole Geology Workshop","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128067494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Full-bore images can be acquired simultaneously; apparent resistivity images from electromagnetic measurements, and acoustic amplitude & transit time images from ultrasonic measurements. The resistivity images provide rich information related to sedimentation style, highlighting the sedimentary structures, textural variation and diaenetic imprints; while the ultrasonic images are more sensitive to fractures and drilling induced features, such as induced fractures and break-out. This innovation LWD tool combines the complementing nature of the high-resolution ultrasonic and electromagnetic image technology without introducing complexity to the drilling bottom-hole assembly in a 15-ft sub. However, many sub-seismic structures (fractures/ faults) are found to be better imaged on apparent resistivity images quite often due to the contrasting features across them. And, a few times even the ultrasonic images could show thin-beds if enough contrast is seen due to cementation along some beds. Therefore, the need of the dual imager is established to image different features for comprehensive geological interpretation, wellbore stability related features and further petrophysical applications","PeriodicalId":427666,"journal":{"name":"Third EAGE Borehole Geology Workshop","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129662187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Borehole image logs were analysed complementary to 3D seismic data, revealing the complex internal architecture at the margin of the channel belt. Extensive folding was detected in the borehole, that was not expected from seismic analysis. Due to the close vicinity to the Alpine fold-and-thrust belt, the origin of these folds was ambiguous and related either to tectonic processes or soft-sediment deformation. Detailed geometric investigations revealed the presence of slump folds that were clearly distinguished from alpine tectonic fold trends. A full characterization of slump geometries was performed and discussed in the context of basin evolution and channel architecture. Fold hinges show significant scatter, suggesting a fairly high complexity of fold geometries, such as higher order folds or refolds. Coherent slump folds were separated from folds with higher complexity and used for subsequent paleoslope analysis. The results show that slumping was not related to gravity flows along the axial channel, but was rather triggered by tectonic movements from the south slope of the Molasse Basin.","PeriodicalId":427666,"journal":{"name":"Third EAGE Borehole Geology Workshop","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127060619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While fractures, faults and karst can often be recognized very well (especially if filled with conductive drilling mud) internal limestone texture is more challenging to identify. However, in some cases, diagenesis can significantly enhance such features and highlight details of the internal composition of carbonate rocks. This amount of detail allows classifying a total of 13 borehole image facies types for the Upper Jurassic limestone reservoir, which are calibrated with borehole cores and cuttings. The borehole image facies interpretation is now used to quality control seismic facies interpretation and further refine it. Vertical stacking of borehole image facies, important stratigraphic marker beds and surfaces reveal the sequence stratigraphic architecture and help to delineate genetically linked depositional units. Flow units (especially associated with karstification) are often found at sequence boundaries. Hence, a robust and validated sequence stratigraphic framework forms an essential part of the geothermal exploration strategy.","PeriodicalId":427666,"journal":{"name":"Third EAGE Borehole Geology Workshop","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127147559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since advent of image log in horizontal wells, low angle bed boundaries which are near-parallel to wellbore and traceable on borehole images for several tens of feet, can hardly be attributed with dips as conventional approach of mathematical sinusoid fails to well-fit bedding features resulting inaccuracy of dip interpretation. This leads to loss of information and restricted interpretation in terms of bedding dips specially in horizontal or highly deviated sections of image. Recently, a new approach has been introduced to trace such bed boundaries in horizontal wells. Quality indicators are also available to ensure proper tracing and hence more accurate dip computation. Instead of the conventional sinusoidal algorithm, this technology contours the lithological boundaries and provides true dip and azimuths of these beds at every desirable sampling interval. This case study shows applicability of the methodology and its implementation in image based high resolution structural analysis of high-angle/horizontal (HAHZ) wells. After comparison with conventional results it is evident that this new way of working with HAHZ well images has an edge over conventional dip analysis method.","PeriodicalId":427666,"journal":{"name":"Third EAGE Borehole Geology Workshop","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130370381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
